Kleinfelter) Newsgroups: comp.sys.att Subject: PBX to 3B2 Message-ID: <1672@msa3b.UUCP> Date: 11 Jun 91 15:27:58 GMT Organization: Dun and Bradstreet Software, Inc., Atlanta, GA Lines: 19 Our AT&T sales thing wants to sell us a 3B2, to hook to our AT&T System 85 PBX. This will provide us with the incoming phone number, and the extension to which it was connected. This is something we'd like to do. The trouble is, they want $80,000 for a 3B2 to do this, and I think it could be done by a $1000 cheap PC, with a serial port. The 3B2 connects to the PBX via a DB25, which the sales rep assures me is asynch serial. I COULD put a line monitor on the line, and reverse engineer the protocol, but I'd like to get the protocol spec. The sales rep seems to go blank at this point. What protocol is used here? Hey, we're commercial -- give me a part number and we'll order the protocol spec. -- Kevin Kleinfelter @ DBS, Inc (404) 239-2347 ...gatech!nanoVX!msa3b!kevin Dun&Bradstreet Software, 3445 Peachtree Rd, NE, Atlanta GA 30326-1276
